Good to Know
- May and September–October are the most comfortable months for nomads: warm enough for outdoor work, low rainfall, manageable crowds, and pleasant afternoon temperatures.
- July–August heat can exceed 35°C (95°F), making midday outdoor activities exhausting; sightseeing is best done early morning or evening. Tourist infrastructure remains active but pricing peaks.
- Winter (November–February) is cold and snowy, but indoor cultural activities (theaters, museums, sulfur baths) thrive and accommodation prices drop significantly.
- Weather can change suddenly in transitional seasons (March–April, November); pack waterproof/quick-drying gear regardless of season.
- Tbilisi receives roughly one-third less annual rainfall than London despite being subtropical, thanks to its valley location and continental influence.
